My first thought on this would be if I can't get daystar to back down by going to the CEO, I should go to the press. Not by accusing Kludge of anything mind you, but by asking questions and letting people draw conclusions (You can only be accused of slander/libel if you make a provably false or misleading statement-questions are not statements. Also you can state any facts you want, no matter how bad it makes someone look, the burden on the party accused is to prove you should have known that you were stating a falsehood when you stated your fact. Also rules on politicians (such as Kludge) are much looser than rules on other people.
"I found out after stopping the super-villain trying to wreck these two buildings that Daystar has been after them to sell their businesses. I wonder if that is a coincidence. I just have to say that if something did happen to deprive these folks of their property rights guaranteed by the fourth amendment, that I would feel unable to enter the establishment that replaced their businesses. I do realize that this would make that establishment the safest place in the city for super-villains and even regular criminals..."
You want to go to a mall known as the place the local hero won't protect? You want to start a business there?
